0X09(CH1)/0X19(CH2)/0X29(CH3)/0X39(CH4) – VERTICAL ACTIVE REGISTER, LOW

BIT

FUNCTION

R/W

DESCRIPTION

RESET

7-0

VACTIVE_LO

R/W

These bits are bit 7 to 0 of the 10-bit Vertical Active register. The two

MSBs are in the CROP_HI register. It defines the number of active video

lines per frame output.

The VACTIVE register has a shadow register for use with 50Hz source when

ATREG of Reg0x1C is not set. This register can be accessed through the

same index address by first changing the format standard to any 50Hz

standard.

0X0A(CH1)/0X1A(CH2)/0X2A(CH3)/0X3A(CH4) – HORIZONTAL DELAY REGISTER, LOW

BIT

FUNCTION

R/W

DESCRIPTION

RESET

7-0

HDELAY_LO

R/W

These bits are bit 7 to 0 of the 10-bit Horizontal Delay register. The two

MSBs are in the CROP_HI register. It defines the number of pixels between

the leading edge of the HSYNC and the start of the image cropping for

active video.

The HDELAY_LO register has two shadow registers for use with PAL and

SECAM sources respectively. These register can be accessed using the

same index address by first changing the decoding format to the

corresponding standard.

0X0B(CH1)/0X1B(CH2)/0X2B(CH3)/0X3B(CH4) – HORIZONTAL ACTIVE REGISTER, LOW

BIT

FUNCTION

R/W

DESCRIPTION

RESET

7-0

HACTIVE_LO

R/W

These bits are bit 7 to 0 of the 10-bit Horizontal Active register. The two

MSBs are in the CROP_HI register. It defines the number of active pixels

per line output.

BIT

FUNCTION

R/W

DESCRIPTION

RESET

This bit is for internal use.

CSBAD

1 = Macrovision color stripe detection un-reliable

MVCSN

1 = Macrovision AGC pulse detected.

0 = Not detected.

CSTRIPE

1 = Macrovision color stripe protection burst detected.

0 = Not detected.

CTYPE

This bit is valid only when color stripe protection is detected, i.e.

CSTRIPE=1.

1 = Type 2 color stripe protection

0 = Type 3 color stripe protection
